具有相同模式的字符串，使用正则表达式组的提取和替换的案例

对具有相同模式的字符串内不同的组的提取怎样做呢,我是这样做的：

提取字符串：sourcetext:{name:john,data:[1,2,3],name:marry,data:[4,5,6]}

代码：

Regex reg = new Regex(@"data:\[([\w|.|,]{1,})\]", RegexOptions.IgnoreCase);MatchCollection matches = reg.Matches(series);foreach (Match match in matches){GroupCollection groups = match.Groups;for (int j = 0; j < groups.Count; j++){string weightjsonInKgMode = covertToKg(groups[j].Value.Replace("data:[", "").Replace("]", ""));string regModel = groups[j].Value;regModel = regModel.Replace("[", "\\[").Replace("]", "\\]");series = Regex.Replace(series, regModel, weightjsonInKgMode);}}

结果：

series中的“1,2,3”，和“4,5,6”，，将分别被weightjsonInKgMode字符串“0.001,0.002,0.003”和“0.004,0.0045,0.0046”所代替
